Hi All, I need some advice on how i could train my German Shepherd to greet visitors calmly. She is about 1.5 years old, sweet and lovely girl, but she gets all jumpy, happy and excited when visitors who she has met before come home. As soon as the door bell rings, she goes nuts, starts barking, pacing around. When my friends come home, she jumps on them and i keep telling my friends to ignore her, but they start petting her, talking to her and she jumps all over them. How can i teach her the right way to greet visitors?
